Does not install gem if installed rake is installed without documents

[func0der]

If I call

gem install --no-document rake
gem install digest-crc

Output:

ERROR:  Error installing digest-crc:

It is important that you NEVER had rake installed with documents, because it somehow remembers them somewhere even after gem uninstall rake.

Also I do not know, why exactly this happens. I thought I would not need rake to build this extension, if I have gcc and make installed on Debian.

Can you reproduce this behavior?

I cannot reproduce using stock ruby-2.5.9.

It is interesting that it found /usr/share/rubygems-integration/all/gems/rake-12.3.1/exe/rake but it cannot execute the file? Can you run the rake command or specifically the /usr/share/rubygems-integration/all/gems/rake-12.3.1/exe/rake file?
